Answer 1

Did you try something like that :
$index = array_search('user_id', $array);
unset($array[$index]);
Do that for all key you want to remove.

Answer 2

$newArray = [];
foreach ($oldArray as $item) {
$arr = [];
$arr['email'] = $item->email;
$arr['username'] = $item->username;
$newArray[] = $arr;
}

Answer 3

Why not create an empty array and just copy the values you need? Trying to unset everything in your array is a lot of work and is not really maintainable, out of experience.
Note that your pasted code contains both an array and object, but your question is about an array only.
$newArray = [];
foreach ($oldArray as $item) {
$newArray[] = [
'email' => $item->email,
'username' => $item->username
]; // If $item is object
$newArray[] = [
'email' => $item['email'],
'username' => $item['username']
]; // If $item is array
}
var_dump($newArray);
